CAIG Laboratories CAIG LABORATORIES DeoxIT D100L-2DB Brush Applicator, More Than A Contact Cleaner, 7.4mL, Pack of 1

I have a few 18650 LED flashlights. A couple I have had for quite a few years. My favorite, kind of a cheapy, has been getting flaky. It has been used a lot over the years. The go to flashlight. Been dropped and beat. Lately it is the tap it against your hand to keep it bright. (We all know that.) On the flashlight forums Deoxit was mentioned and I was skeptical. But I would give it a try. It sat on the garage shelf for a while and I picked up one of my other LED flashlights. It has been dim for a while, I thought it was just going bad. Yesterday was the day. I took it to the bench and completely dissembled it. Switch (clicky) and all. I wiped all the dirty threads down clean (with a paper towel) and took the brush to all the metal contacts. Even hit the battery terminals and all the spring ends. It does not take much. Just a tiny amount. Well the dim light was just as bright as new. Really surprised me. So next was the old go to. Did the complete cleaning and hit every contact surface with the Deoxit. Put it back together and it was back to old reliable. I decided to do a few other flashlights. They all work like new. Was it the cleaning and retightening? Did Deoxit help? Guessing so I tried cleanings before without much luck. OK I did not use a lot. Very little amounts. After all the contact surfaces in 4 flashlights, it is barely down to the top of the label. Heads up the D100 is a small bottle. It is the size of a finger nail polish bottle. Kind of expensive for the little amount you get. But seems to be worth it. Also... D100L-2DB is 7.4 ml the size of a small nail polish bottle. The D100L-2C is 2ml... Not very much... But may be about what I used on the 4 flashlights. You don't need much. I am not sure if I would get a spray can. You would probably spray most any where but where you need it. One thing not sure of. Will it keep the threads from seizing? These aluminum flashlights can gall the aluminum threads and lock them together. Will Deoxit prevent that?? Time will tell. If you have scratchy or intermittent electrical contacts, I would give it a try.

Muy buen producto pero añadid al precio de venta casi 7 euros que te meten en la aduana española.

Works as described, highly recommended!

saved me a huge amount of money, since i did not have to change the computer in my truck.
